Gives optional customizable lines of Flavor text for different stages of mechanical arousal (#4801)

## About The Pull Request

Adds three new small input fields in the Character Lore section.
these are short flavor text for low, medium, and high arousal.
they will show up when being examined while mechnically aroused and both
the examiner and examined have ERP interactions turned on in their
prefs.
Leaving the fields blank also stops any flavor text from showing up for
that arousal level

From what I can tell the implemented feature works fine. 
Minor issue remains in that the fields to enter these flavor texts are
ordered a bit weird. If anyone who knows how fix that, please tell me.
## Why It's Good For The Game

Currently, mechanical arousal has either no impact or is annoying and
distracting.
This change hopes to make mechanical arousal actually add to the
roleplay rather than distracting from it.
This should hopefully also make the arousal system actually usable for
other features.
## Proof Of Testing

From what I can tell the implemented feature works fine.
